My invention relates to valves, and particularly to that classofvalvesused to stop thefiow through branch or main pipes, and the objects of myimprovements are:

First, to provide a neat, simple andeconomical valve to replace the moreclimbersomecut-out cocks. l

Second, to provide avalve whichalso takes the place of a union and maybe installed in a pipe line withoutturning either of the pipes to "whichit is connected, and third-to provide a valve which may be readilytakenapart for inspection or to replace the re-I movable valve seat; Otherobjects and advantages will appear later in the specification andreferred more In the'drawingaFigure 1 is a side plete valve.

Figure 2 is a plete valve showing the interior off'same.

' member (k) .AS will be seen from the drawing this valve has no handleand it normally remains in anopenosition. It is closed only when it isdesire to stop the passage of water,

steam, oil, gas, air, etc, through the pipe, as for instance when makmg'repairsbeyond this point in the pipe line. I

.I do not wish to be limited to the details of construction or useherein set forth, but

case the joint would be reserve the right to change, modify, or'vary theconstruction within the scope of this lnvention. a y

Having thus described my invention, what I claim and desire to secure byLetters Pat cut, is--- Y V 1.- A valve comprising a nipple having alongrunning thread one end of which forms a valve seat, and end memberinternally and externally threaded at each end, an in- Y ternal annularvalve member provided with a plurality of-ports and carrying a removableground valve or washer and a detent" rovided between the valve or washerand its holder, an intermediate annular memberfprovided with a chamberforming a by? pass around the end of said valve member when open andanannular lip formed on one .end of said intermediate member and a packing nut to co-operate therewith to enclose a a packing,

2. In a device of the classdescribed, in combination with a nipplehaving a ground seat, of a valve member provided with one or moredetents to engage a washer and prevent same from turning with referenceto the valve member, a paekin member provided with an overhanging lip, apacking and jam nut having a beveled flange, and both packing member andpacking nut mounted on a traveling thread on the nipple.

3. In a deviceof the class described, in combination; a nipple providedwith a relatively long threaded portion on the end of which is provideda'valve seat, an intermediate member having internal threads at bothends, the inside diameter of a part of which is relatively larger thanthe other part to form a bypass around the end of the valve holder, aremovable ground valve head, an internal valve member being partiallyhollow provided with a plurality of ports in the lateral wall thereofand an end member to which said valve and intermediate members areconnected.

4. In a device of the class described, in combination with a nipplehaving a long thread, a packing nut, packing and a middle member mountedon said threaded part of the nipple, a valve member provided with one ormore ports, a washer secured to said member and held from turning onsame by meansof detents, a by-pass around the end of said valve memberwhen same is open, and anend member provided with an outer and innerthreads.

In testimony whereof I aflix my signature.
